The 2026 Formula Pro USA Western Series is the seventh season of the championship for Formula Regional and Formula 4 cars established on the West Coast of the United States. The championship is promoted and organized by Exclusive Racing and Exclusive Auctions, and is run under the same sporting regulations as the FIA-sanctioned Formula Regional Americas Championship and Formula 4 United States Championship.
It began in March, with the championship spanning six weekends until November. [1]
Drivers are able to enter either the FPUSA-3 or the FPUSA-4 class, with the former using a Ligier JS F3 car and the latter a Ligier JS-F4 car. All cars are powered by Honda and use Avon tires. [2]
